Definition of Critical Value: "...is a laboratory test result that represents a pathophysiologic state at such variance with normal as to be life-threatening if an action is not taken quickly and for which an effective action is possible. ..."Source: MedGenMed. 2007; 9(1): 20.

Definition of Vital Value: "...is a laboratory result just as important as a critical value, but one for which timing is not as crucial. While a blood glucose under 40 mg/dL is a critical value, positive Pap smears, mammograms, or TB cultures are examples of vital values. ..." Source: MedGenMed. 2007; 9(1): 20.
